How long does this stay charged? In other words, can I keep it in a vehicle for emergencies?

You'll have to charge it every few days if you keep in in the charge; but beware! In the summer, the portable charger will discharge much faster! I keep it in my backpack. But you will have to recharge it after use.

No, it runs down. You would have to recharge it every few days at minimum I would say.

This product has an on/off switch so its standby current should be very low. The internal lithium-ion battery has a long shelf life (over 1 year) when stored at room temperature. When stored in a car during summer time, the high temperature during day time will cause the battery to self-discharge faster. I recommend you should recharge it once every 3 months just for the peace-of-mind.

I can't say from experience yet but but lithium batteries usually hold their charge relatively well. I would recommend a cigarette lighter plug with a USB adapter. That way you can charge your phone, the spare battery/light and what ever else you wanted.

You can charge it in about 2 or 3 hours. I found a trick that if you make sure it stays cool, it will charge quicker and discharge slower. Not a bad battery.

Yes If you read the short little manual it tells you it will hold a charge up to three months. Depending on the amount of use of course. Any rechargeable item you should not try to leave in any longer than it takes to charge the item. Don't charge again until empty or preparing for a trip to ensure a good charge.

I can't answer exactly, because I use it for quick pick ups. I actually have never had it run out of a charge but occasionally I just plug it in.

Yep, I was hoping to see reviews on it too. ALSO, I'm wondering if you charge it up and leave it in your trunk, how long does it retain the charge. I.E., sit for a year and still be able to be used to 'jump' a car?

This is a great unit. Be sure to give it a full initial charge! After that, you can carry it in your automobile for up to 60 days before recharging. However; be sure to charge it AFTER EACH USE. Also, there is a neat little button on the unit's face that indicate any need for a charge.

Mine I've charged twice since about 8 months ago and its always pretty full. I only use in emergency as well but i can always guarantee it will at least be at the % i left it at last. Its probably loses battery about as much as your normal energizer battery not in use.

Hi Eric, I keep this charged and stored in my computer case. The longest I've had it charged without using it was three weeks. It seemed to have kept a full charge during that time. I hope this helps.

It will start making a warning tone. The first time it happened to me I didn't realize it was the speaker, I thought my phone was broken. You can use the speaker while its being charged. I charge my speaker on e a week, while driving, and it usually always last for the 7 days without a recharge.

I would recommend getting a electrical charger. This one is more for something that you don't drive very often like a atv or a lawnmower. This only being 2.4 watts, isn't powerful enough to charge a car battery. It's really just for maintaining. I bet it would take a long time to fully charge a car battery.

The GunBox has a battery inside of it, so you can still access it during a power outage. I personally keep mine plugged in all the time, in case the power goes out, it will still hold a charge. I believe that fully armed, it will hold a charge for approximately 8-12 hours. If you turn off the "movement alarm" and everything else (except the fingerprint, of course) it will hold a charge for a few days. Bottom line - during a power outage, you will definitely still be able to access your GunBox, as long as it has been plugged in to power.

I have it as a back up in an alarm system, and they have lasted one or two years before needing replacement. It is constantly kept charged by the alarm system. Then we get a call from the alarm company when it no longer stays charged, needing replacement.

I plug in when I get in my car. It puts a fair charge to phone in my 30-45 minute trips. Enough to stay charged while on the run. Convenient when you've forgotten to charge at home

You can keep it in your car, but realize that cold temps will make it much weaker if and when needed. Keeping it charged is the biggest factor in making it last, so keep that up if you want it to have a chance at working.

The end that charges the item has to be plugged into a USB receiver. Either a PC or an iPhone plug that plugs into the wall. To add to my last review... I must say that after re-charging it and using it a few times, it seems to be holding a charge way longer then the first time, making it more handy to have for emergencies! I'm considering purchasing another for my teenager. Hope this helps!

No, the battery cannot be overcharged. But I would not leave it on 'charge' indefinitely.

The battery is housed inside the device. To the right of the antenna theres a plug to charge (9-12VDC), it takes twelve hours to charge for the first charge. Every charge thereafter is four or six hours (double check instructions). The device is mobile. Its a good battery, I've only charged it once, I havent needed it. Maybe a handfull of places I've actually swept a specific area and ive had it for eight months. I wouldnt leave the device plugged in the wall too long after its charged, you'll decrease battery life.
